Brother dull, seeking God to help look great with sbjson how to resolve this json

functionString = [{\ "TYPE \": \ "Printer \",
\ "CONFIGDATA \":
[{
\ "DCONF_ID \": \ "207 \",
\ "D_FUN \": \ "powered \",
\ "D_TYPE \": \ "zigbee \",
\ "D_VA \": \ "d401 \",
\ "D_STATE \": \ "available \"
},
{\ "DCONF_ID \": \ "208 \",
\ "D_FUN \": \ "off \",
\ "D_TYPE \": \ "zigbee \",
\ "D_VAL \": \ "d400 \",
\ "D_STATE \": \ "available \"}]
},
{\ "TYPE \": \ "cooker \",
\ "CONFIGDATA \": \ "NULL \"
}]




Mainly following null;
SBJsonParser * parser = [[SBJsonParser alloc] init];
NSMutableArray * array = [[NSMutableArray alloc] initWithArray: [parser objectWithString: functionString]];
for (NSMutableDictionary * singleHomAppFunctions in array) {
NSMutableArray * arr = [singleHomAppFunctions objectForKey: @ "CONFIGDATA"]; / / is this sentence I received directly by the collection, then get the following CONFIGDATA of "NULL", an error occurs. . . . . . . . Great God Yeah, this supposed to die? ? ? ? , Seeking to guide! ! ! !

This is an array format. Very common.
I use JSONDecoder class to parse. Very simple. Such analytical methods are

NSDictionary * json = [subjson objectForKey: @ "functionString"];
NSArray * responseObject = [json objectForKey: @ "CONFIGDATA"];
This will put the array. If you do not understand, please contact me, I write you a demo presentation.

You are not the outermost whole less ""

NSString * jsonStr = @ "{\" data \ ": {\" count \ ": \" 14 \ ", \" list \ ": [{\" groupName \ ": \" My friends \ ", \" friendList \ ": [{\" name \ ": \" Phone1 \ ", \" imagename \ ": \" head01 \ "}, {\" name \ ": \" Phone2 \ ", \" imagename \ ": \ "head02 \"}]}, {\ "groupName \": \ "colleague \", \ "friendList \": [{\ "name \": \ "Phone3 \", \ "imagename \": \ " head03 \ "}, {\" name \ ": \" Phone4 \ ", \" imagename \ ": \" head04 \ "}, {\" name \ ": \" Phone4S \ ", \" imagename \ ": \ "head05 \"}]}, {\ "groupName \": \ "My XX \", \ "friendList \": []}]}, \ "mesage \": \ "Operation successful \", \ "status \": \ "0 \"} ";
So that it can be resolved
